I've got it so bad that I've been through three or four single H Bongo fivers just because I wanted a different COLOR.
Really.
I've mentioned this before, but the secret is to get up to about eight or ten basses and keep them constantly rotating in and out so the wife gets used to the idea of trades and, of course, boxes coming from the UPS guy.
After a while, they aren't even curious.
It's just another box, just another, ahem, 'trade'.
